Overview
The Civil Aviation Safety Regulations 1998, established by the Commonwealth of Australia, aim to maintain and ensure the safety of civil aviation in the country. These regulations were enacted to address the need for stringent safety standards and to mitigate the risks associated with civil aviation activities. The Civil Aviation Safety Authority (CASA) is the body responsible for enforcing these regulations, with a key policy objective being to ensure the highest possible safety standards in civil aviation. A notable legislative instrument under these regulations is the Airworthiness Directive (AD) AD/TB20/39 issued for Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes. This directive, effective from 4 October 2001, was introduced in response to a manufacturing fault identified in the nose gear fork of specific TB20 and TB21 aircraft models. The directive mandates corrective action in accordance with Socata Service Bulletin SB 10-119-32, dated June 2001, to be undertaken during the next scheduled maintenance visit between 4 October 2001 and 31 March 2002.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) delegate, pertains to Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes with particular serial numbers. This AD mandates corrective action for a fault identified in the nose gear fork manufacturing process of the specified aircraft, aimed at ensuring the aircraft's airworthiness. The directive applies to TB20 and TB21 aircraft with certain serial numbers and requires compliance with the instructions outlined in Socata Service Bulletin SB 10-119-32, dated June 2001. The directive mandates that the corrective action be undertaken during the next scheduled maintenance visit after 4 October 2001 or before 31 March 2002, whichever is earlier. This directive, effective from 4 October 2001, is issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 and is notified in the Commonwealth of Australia Gazette on 12 September 2001.
Key Provisions
The Civil Aviation Safety Regulations 1998, under subregulation 39.1 (1), establish a framework for issuing Airworthiness Directives (ADs) to address safety issues in civil aviation. Section 105 of the Civil Aviation Safety Regulations 1998 specifically pertains to the issuance of these directives by a delegate of the Civil Aviation Safety Authority (CASA). In this particular case, AD/TB20/39 is issued for Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes to address a manufacturing fault in the nose gear fork.
The AD applies to specific serial numbers of TB20 and TB21 aircraft, namely those with serial numbers 1893, 1894, 1896 through 1899, 1901, 1902, 1904 through 2021, 2023 through 2033, 2035, 2036, and 2038. The directive requires that corrective action be taken in accordance with Socata Service Bulletin SB 10-119-32, dated June 2001. This action must be performed at the next scheduled maintenance visit after 4 October 2001, or before 31 March 2002, whichever occurs first. The directive was issued on 24 August 2001 and became effective on 4 October 2001.
The AD imposes obligations on the owners and operators of the affected aircraft. They must ensure that the specified corrective action, as outlined in the Socata Service Bulletin, is carried out by a qualified maintenance technician. This involves inspecting and potentially replacing or repairing the nose gear fork to correct the identified manufacturing fault. The directive was notified in the Commonwealth of Australia Gazette on 12 September 2001 to ensure widespread awareness among the aviation community.
Failure to comply with this AD may result in the aircraft being deemed unairworthy, which could lead to grounding and potentially severe civil or criminal penalties. The exact penalties would depend on the specific circumstances of the non-compliance and any resultant safety incidents. The seriousness of the issue and the potential impact on flight safety underscore the importance of adhering to the requirements set out in the AD.
